Hello, George I'm an independent advisor and I will try to help you today.
According to your query, first check if the system somehow recognizes the unit. For it:
- Press the Windows keys + X at the same time, and from the list that appears select the "Disk Manager"
- Then right-click on the drive and select "Change drive letter", assign a letter and check if it already appears in the file explorer.
If it doesn't work, try changing the cable as well, sometimes that causes the problem.
On the other hand, also check that you have your updates up to date,
- Press Windows keys + I
- Select Update & Security.
- Go to the Troubleshooter option.
- Select Windows update
- Then click on check for updates and then install them and reboot.
